No, no. How did it get to London from hence? For from this country it came. I suppose the English brought it home in Queen Bess's or James the First's time. But if it is wild here, and will grow so well in England, why do we not find it wild in England too? For the same reason that there are no toads or snakes in Ireland. They had not got as far as Ireland before Ireland was parted off from England. And St. Patrick's cabbage, and a good many other plants, had not got as far as England. But why? Why, I don't know. But this I know: that when Madam How makes a new sort of plant or animal, she starts it in one single place, and leaves it to take care of itself and earn its own living--as she does you and me and every one--and spread from that place all round as far as it can go. So St. Patrick's cabbage got into this south-west of Ireland, long, long ago; and was such a brave sturdy little plant, that it clambered up to the top of the highest mountains, and over all the rocks. But when it got to the rich lowlands to the eastward, in county Cork, it found all the ground taken up already with other plants; and as they had enough to do to live themselves, they would not let St. Patrick's cabbage settle among them; and it had to be content with living here in the far-west--and, what was very sad, had no means of sending word to its brothers and sisters in the Pyrenees how it was getting on. What do you mean? Are you making fun of me? Not the least. I am only telling you a very strange story, which is literally true. Come, and sit down on this bench. You can't catch that great butterfly, he is too strong on the wing for you. But oh, what a beautiful one! Yes, orange and black, silver and green, a glorious creature. But you may see him at home sometimes: that plant close to you, you cannot see at home. Why, it is only great spurge, such as grows in the woods at home. No. It is Irish spurge which grows here, and sometimes in Devonshire, and then again in the west of Europe, down to the Pyrenees. Don't touch it. Our wood spurge is poisonous enough, but this is worse still; if you get a drop of its milk on your lip or eye, you will be in agonies for half a day. That is the evil plant with which the poachers kill the salmon. How do they do that? When the salmon are spawning up in the little brooks, and the water is low, they take that spurge, and grind it between two stones under water, and let the milk run down into the pool; and at that all the poor salmon turn up dead. Then comes the water-bailiff, and catches the poachers. Then comes the policeman, with his sword at his side and his truncheon under his arm: and then comes a "cheap journey" to Tralee Gaol, in which those foolish poachers sit and reconsider themselves, and determine not to break the salmon laws--at least till next time.
